Bullying is a considerable problem among school students, and school-wide positive behaviour support interventions are regarded as helpful in addressing it. One approach is the CATZ Cross-age Teaching Zone anti-bullying intervention. The present study assessed the social validity of the CATZ anti-bullying intervention among a sample of…

Measuring the implementation fidelity (IF) or integrity of interventions is crucial, otherwise a positive or negative outcome cannot be interpreted. Direct and indirect methods of IF measurement tend to over-emphasize teacher behaviour. This paper focuses on IF measured by student behaviour collected through computers. Attainment was measured by…

In the UK, students who want to progress to higher education have a number of possible pathways at age 16. The most common of these is traditional, academic focussed, 'A' levels, but increasingly students are taking alternative qualifications (e.g. BTECs, IB, Pre-U). The focus of this research is to infer which (if any) of these qualifications are…

For a number of reasons, increasing reliance is being placed on teacher assessment in high-stakes contexts in many countries around the world. Simultaneously, countries that have for some time relied to greater or lesser degrees on teacher assessment for high-stakes purposes are in the process of questioning the validity of that reliance. In…

In recent years, there have been concerns in the UK regarding the uptake of particular subjects in post-compulsory education. Whilst entries for Advanced level (A-level) subjects such as media studies have experienced considerable growth, entries for A-level physics have, until recently, been declining, prompting fears of a skills crisis in future…

"Item difficulty modelling" is a technique used for a number of purposes such as to support future item development, to explore validity in relation to the constructs that influence difficulty and to predict the difficulty of items. This research attempted to explore the factors influencing question difficulty in a general qualification…

Much of the argument about comparability of examination standards is at cross-purposes; contradictory positions are in fact often both defensible, but they are using the same words to mean different things. To clarify this, two broad conceptualisations of standards can be identified. One sees the standard in the observed phenomena of performance…

The rank-ordering method for standard maintaining was designed for the purpose of mapping a known cut-score (e.g. a grade boundary mark) on one test to an equivalent point on the test score scale of another test, using holistic expert judgements about the quality of exemplars of examinees' work (scripts). It is a novel application of an old…

Robert Coe has claimed that three broad conceptions of comparability can be identified from the literature: performance, statistical and conventional. Each of these he rejected, in favour of a single, integrated conception which relies upon the notion of a "linking construct" and which he termed "construct comparability".…
